Abstract
A method and apparatus for cell handover and reconfiguration includes: performing cell measurement and reporting a result of measurement by UE according to a cell measurement request; detaching, when the UE receives a handover command transmitted by a macro eNB or a serving eNB of the UE, from the serving eNB by the UE and reserving an uplink time adjustment parameter NTA of the serving eNB by the UE; and performing cell handover and reconfiguration by the UE according to the handover command. With the method and apparatus of the embodiments, When the UE is still in a state of being connected to the serving eNB, the target eNB begins to detect its uplink signal to determine uplink time advance of the UE and the target eNB, and the UE replaces the source serving eNB with a new target eNB according to indication of other cells.
